Secured to discharge pipe entering the hot well 17 and ofthe Y 12, is a'short pipe section 19, within which is disposed a valve 20 provided with an arm 21 secured to the spindle 2.2 of the valve which is extended. out through the wall of said section, and to this arm is connected by the rod 23, the crank arms 25 and 26-, and the pivot pin 27, the float 24 located within the condenser.

Secured to the section 19 is the discharge pipe 28, rovided with the check valve 29', the end o which extends into the hot well 17 and below the normal level of the water therein, the division plate.30 being provided in the hot well between pipes 15 and 28,"if the hot well is so small that the ends of said pipes are situatedlcomparatively close together in order that air discharged throu h pipe '15 may not enter pipe 28 and eventual y i return to the condenser 1f the flow. of water through pipe 28 should not be very rapid.

The numeral 31 designates the overflow pipe for the hot well; and the numeral 32 designates a check valve in the dry. air pipe, this check valve being provided so that the water forced by the ump 9 in starting the condenser with forced injection through pipe 3 will not back up through the dry air pipe 6 into the condenser before the Water has attained sullicient velocity to overcome the back pressure of the atmosphere and open check valve 16 and flow to the hot well;

The 0 eration of the a paratus thus far describe( is as follows: '1 e steam entering at 2. encounters the cold -water' entering and the umbrella 5, and. is condensed. The Water of condensation and the condensing water both fiow downward into pump 9 and are thrown out through the ejector 1'4, 1 whereby the air is entrained. through dry air pipe 6, and the commingied air and water are discharged through pipe 15 into the hot 5 well 17, the valve 20 ordinarily remaining closed, especially during the winter season. I Shoiild, however, the water level in the condenser rise above the normal, as indicated by the line 132, by reason of more water being supplied from anypause whatever, the Heat i valve 20 will close.

24 will rise and open the valve 22, allowing the excess of water to be discharged by the ump through pipe 28, and when the water evel in the condenser falls again to normal,

The use of the ej cctor '14, or any equivalent a paratusfor removing the air, necessitates t e flow of a maximum ,quantityotrvater at all times to render the effective, and if itiverenot for the provision of the additional pipe 28, or its erpiivalent, the pump 9 would be compelledto ejector eliieient and t andle at all times and under allcircunistanoe's the greatest amount of water that would be requiredduring the veryhottest weather of a long hot summer, which would not lie-economical of power in the operation of the j, 1

By, however, usin an ejeetorior withdrawing air from the con enser, which ejector is .designed. to use the minimum amount ofwater which it may be required to discharge from theeondenser o and an additional discharge. assage, the sinle pump is enabled t ooper orm ts service rom minimum to maximum load while rune ning at a 'eonstant speed and, at the s'ame 4 1 time remove the air from the condenser.

' 1he apparatus shown by Fig. 3 embodies the same general princip s of design and 1 operation as the apparatus disclosed by Fig.

1. Referring to-Fig. 3, the numeral 100 designates the condenser, ZOOthe'Stcam inlet,

300 the condensing water inletfdOOffthe spraying controlling valve, 500 the umbrella,

600 the dry air pipe, and 700 lugs upon which the condenser maybe supported. The conde nser is open at its lower end and provided with a flange whichis adapted to be, secured to a T 101, the dry air pipe being provided to be secured to the opposite branch of t .e T and the discharge pipe 107 elxten'dc'd below the surface of the watcr'in the hot well 108,

cure to the ejector nozzle 106.

Within the T 101 and extended into the ejector nozzle 15 6, is the contracted nozzle and rovidcd with the check'v'alve 109, is 'se- 110 through which the water discharged by the ump 1s forced;attaining a high velocity at t 10 extremity of said nozzle, thereby producing an e'ector effect in the space 1 1 1, with 5 the result t at the air in the condenser flows down through the dry air pipe 600 and is withdrawn y the discharge of the Water. To render this arrangement of the apparatus adapted to handle different quantities of water, the nozzle 1-10 is made adjustable so that its outlet area may be varied. This ma be effected, see Figs. 4 and 5 by the two sh ing gates112 and 113, which are adaptedto be moved horizontally of said nozzle by the intermeshing gears 114 and 115, the pinions 1 16 and 117secured to the shafts 118 and 1 19, the pinion's ineshin with rack teeth provided upon said Fates. he end of the nozzle 110 is provider in the structure illustrated by the drawings with two oppositely dis osed slots the sides of. which are parallel an providedwith ways within which the gates are adapted to slide, these ways being extended fartherup the nozzle than the slots.

By Figs. 6 and 7 are illustrated an e uivalent slide operating device, the slides eing provided with theslotted wings '120, 121, within the slots of which pins secured to crank arms-122 and 123 are adapted to'slide, said crank arm's being connected respectively with sha'ft's 124,125, which extend out through the casing and areprovided at their outer ends with cranks- 126* and 127, which are in turn connected by means of pins with a common actuating lever'12'8,pivotcd to the casin 4 The construction and arrangement of the apparatus shown by Fig. 8Jis-iri all respects similar to thatf shown 'hy Fig; 3, except that the nozzle1100is-n'otad'u'stable, the constructionbeing' such that? tl is'nozzle may be readily removed and m la'ce'd by one of a different 'size- The nozzle 1100 terminates in a nozzle'mouth" as in the aforedescribed modification; f

The constructionandarrangement of apa'retus described and'illu'strated provides a very simple and efficient condenser plant. The 'pump'being located directly heloui' the cmdense'r, cannot get air boimd, space is economized,.- a minimum of piping is refibquired, and the-dry,air'pipejcan be made very large so. as to ofiefthe minimum resista'ncetothefiow of"tl'iefairand attenuated gases -therethrough:- It will of course suppliedto e condenser-of tlieft'yrpe' disclosed eral type disclosed by t be"undc'rstood by those versed'in'the art, thatthe; amount of'w'atcr,
